Can I fill any PDF form with this tool?

Yes. The tool supports all standard PDF interactive form fields (AcroForm). If your PDF has fillable fields, they will be detected and available for input. For non-interactive PDFs (no form fields), use the Form Creator tool to add fields first.

Is my form data stored anywhere?

No. All form data is processed locally in your browser. Your responses, personal information, and signatures are never uploaded to any server. This is especially important for forms containing sensitive data like tax forms, medical forms, and legal documents.

Can I save a partially completed form?

Yes. You can download the form at any point with your current entries saved. Re-upload it later to continue filling. The partially completed form retains all your entries.

What does flattening do?

Flattening converts interactive form fields into static page content. After flattening, the form data becomes part of the page and cannot be edited. This is useful for creating a final, non-editable version of a completed form.
